CPU Role

The AMD Ryzen 7 5700G is a desktop processor built on the Zen 3 architecture (Cezanne) with 8 cores and 16 threads. Its base clock is 3.80 GHz and boost clock reaches 4.60 GHz, with a TDP of 65 W. The CPU supports DDR4 memory in dual-channel configuration, providing 51.2 GB/s of memory bandwidth. The cache hierarchy includes 64 KB L1 per core, 512 KB L2 per core, and a 16 MB L3 cache. These specifications contribute to strong single-thread performance, as evidenced by a Cinebench R23 single-core score of 2930 and a Passmark single-thread score of 3283. In Roblox, which relies heavily on game logic and physics, such single-thread capability is critical. The CPU's multi-threaded scores—Cinebench R23 multi-core 20755, Geekbench multi-core 8970, and Passmark multithread 24419—indicate ample headroom for background tasks, though Roblox may not fully utilize all 16 threads. The CPU's percentile ranking of 83 means it outperforms 83% of all CPUs in the benchmark database. Compared to its nearest rivals, the Ryzen 7 5700G is 0.3% behind the AMD Ryzen 7 6800U (avg score 25706) and 0.4% ahead of the Intel Xeon D-2752TER (25532), with similar margins over the Intel Core 5 210H (0.5%) and AMD Ryzen 5 7640U (0.6%). This places the CPU in a competitive mid-range position, though not at the top tier.

GPU Role

The AMD Radeon RX 570 is a discrete GPU based on the Polaris 20 chip (GCN 4.0 architecture) manufactured on a 14 nm process. It features 2048 shading units, 128 texture mapping units, and 32 ROPs. The GPU operates at a base clock of 1168 MHz and a boost clock of 1244 MHz, with 4 GB of GDDR5 memory on a 256-bit bus, yielding a memory bandwidth of 224.0 GB/s. The memory clock is 1750 MHz (7 Gbps effective). The GPU's FP32 performance is 5.095 TFLOPS, and it supports DirectX 12 (12_0), OpenGL 4.6, and Vulkan 1.3. The RX 570's average benchmark score is 30158, placing it in the 74th percentile of all GPUs. Its nearest rivals include the NVIDIA GeForce RTX 5060 (avg score 30109, delta 0.2%), AMD Radeon RX 7700 XT (30097, delta 0.2%), NVIDIA Tesla M60 (29969, delta 0.6%), and NVIDIA GeForce RTX 5070 Mobile (29928, delta 0.8%). The GPU's 4 GB VRAM is sufficient for Roblox's relatively modest texture requirements, but the card's age and architecture become evident at higher resolutions. The launch MSRP of the RX 570 is 169 USD.

Measured FPS Breakdown

The measured FPS data for Roblox with this combo is as follows:

| Resolution | Settings | Avg FPS |

|------------|----------|---------|

| 3840x2160 | High | 44.3 |

| 3840x2160 | Low | 53.7 |

| 3840x2160 | Medium | 49.1 |

| 3840x2160 | Ultra | 37 |

| 2560x1440 | High | 77.9 |

| 2560x1440 | Low | 98.2 |

| 2560x1440 | Medium | 87.4 |

| 2560x1440 | Ultra | 67.6 |

| 1920x1080 | High | 121.7 |

| 1920x1080 | Low | 149.5 |

| 1920x1080 | Medium | 132.3 |

| 1920x1080 | Ultra | 96.8 |

At 1080p, all settings deliver average FPS above 60, with Low reaching 149.5 and Ultra still at 96.8. At 1440p, the lowest setting (Low) hits 98.2, while Ultra drops to 67.6—still above 60. At 4K, the picture changes dramatically: even Low only manages 53.7 FPS, and Ultra falls to 37. The data shows a clear progression: as resolution increases, the GPU becomes the limiting factor, and the gap between settings narrows in absolute terms but remains proportionally significant.

Resolution Scaling

The FPS drop from 1080p to 4K is steep across all settings. For High, the average FPS goes from 121.7 at 1920x1080 to 77.9 at 2560x1440, and then to 44.3 at 3840x2160. Low follows a similar pattern: 149.5 to 98.2 to 53.7. Medium moves from 132.3 to 87.4 to 49.1, and Ultra from 96.8 to 67.6 to 37. The reduction from 1440p to 4K is more severe than from 1080p to 1440p, indicating that the GPU's pixel throughput and memory bandwidth are insufficient for 4K rendering in Roblox. At 1080p, the CPU's strong single-thread performance likely keeps the frame rate high, but as resolution climbs, the GPU's 4 GB VRAM and 224.0 GB/s bandwidth become bottlenecks. The fact that even Low settings at 4K cannot reach 60 FPS suggests that the RX 570 is not suited for 4K gaming in this title, regardless of quality presets.

Settings Recommendations

Based on the measured rows, the optimal settings depend on the target resolution. At 1920x1080, Ultra provides an average of 96.8 FPS, which is smooth and visually rich; there is no need to lower settings for performance. At 2560x1440, Ultra still delivers 67.6 FPS, comfortably above 60, so Ultra is recommended for a balance of quality and fluidity. At 3840x2160, no preset reaches 60 FPS; the highest average is Low at 53.7, which is playable but not ideal. For 4K, Low is the only viable option, and even then, the frame rate hovers near 50. The data suggests that this combo is best used at 1080p or 1440p with Ultra settings, while 4K should be avoided or reserved for Low settings with the understanding that performance will be sub-60. The combo's low rank (1744 out of 1800) in Roblox reinforces that this hardware is not optimized for high-resolution play in this sandbox title.
